nents, unless the components are constructed of materials which are inherently

resistant to being corroded or are suitably protected against being so corroded.

Repair and maintenance to electrical components shall include initial safety

checks and component inspection procedures. If a fault exists that could

compromise safety, then no electrical supply shall be connected to the circuit

until it is satisfactorily dealt with. If the fault cannot be corrected immediately

but it is necessary to continue operation, an adequate temporary solution

shall be used. This shall be reported to the owner of the equipment so all

parties are advised.

Checking for presence of refrigerant

The area shall be checked with an appropriate refrigerant detector prior to and

during work, to ensure the technician is aware of potentially toxic or flammable

atmospheres. Ensure that the leak detection equipment being used is suitable for

use with all applicable refrigerants, i.e. non-sparking, adequately sealed or intrinsi-

cally safe.

Presence of fire extinguisher

If any hot work is to be conducted on the refrigerating equipment or any associated

parts, appropriate fire extinguishing equipment shall be available to hand. Have a

dry powder or CO2 fire extinguisher adjacent to the charging area.

No ignition sources

No person carrying out work in relation to a refrigerating system which involves

exposing any pipe work shall use any sources of ignition in such a manner that it

may lead to the risk of fire or explosion. All possible ignition sources, including

cigarette smoking, should be kept sufficiently far away from the site of installation,

repairing, removing and disposal, during which refrigerant can possibly be released

to the surrounding space. Prior to work taking place, the area around the equipment

is to be surveyed to make sure that there are no flammable hazards or ignition risks.

"No Smoking" signs shall be displayed.

Ventilated area

Ensure that the area is in the open or that it is adequately ventilated before breaking

into the system or conducting any hot work. A degree of ventilation shall continue

during the period that the work is carried out. The ventilation should safely disperse

any released refrigerant and preferably expel it externally into the atmosphere.

Checks to the refrigeration equipment

Where electrical components are being changed, they shall be fit for the purpose

and to the correct specification. At all times the manufacturer's maintenance and

service guidelines shall be followed. If in doubt, consult the manufacturer's technical

department for assistance.

Checks to electrical devices

Repairs to sealed components

During repairs to sealed components, all electrical supplies shall be disconnected

from the equipment being worked upon prior to any removal of sealed covers, etc.

If it is absolutely necessary to have an electrical supply to equipment during servic-

ing, then a permanently operating form of leak detection shall be located at the most

critical point to warn of a potentially hazardous situation.

Particular attention shall be paid to the following to ensure that by working on

electrical components, the casing is not altered in such a way that the level of

protection is affected. This shall include damage to cables, excessive number of

connections, terminals not made to original specification, damage to seals, incor-

rect fitting of glands, etc.

– Ensure that the apparatus is mounted securely.

– Ensure that seals or sealing materials have not degraded to the point that they no

- 4 -

longer serve the purpose of preventing the ingress of flammable atmospheres.

Replacement parts shall be in accordance with the manufacturer’s specifications.

NOTE: The use of silicon sealant can inhibit the effectiveness of some types of leak

detection equipment. Intrinsically safe components do not have to be isolated prior

to working on them.

Repair to intrinsically safe components

Do not apply any permanent inductive or capacitance loads to the circuit without

ensuring that this will not exceed the permissible voltage and current permitted for

the equipment in use.

Intrinsically safe components are the only types that can be worked on while live in

the presence of a flammable atmosphere. The test apparatus shall be at the correct

rating.

Replace components only with parts specified by the manufacturer. Other parts

may result in the ignition of refrigerant in the atmosphere from a leak.

Cabling

Check that cabling will not be subject to wear, corrosion, excessive pressure, vibra-

tion, sharp edges or any other adverse environmental effects. The check shall also

take into account the effects of aging or continual vibration from sources such as

compressors or fans.

Leak detection methods

Leak detection fluids are suitable for use with most refrigerants but the use of deter-

gents containing chlorine shall be avoided as the chlorine may react with the refrig-

erant and corrode the copper pipe-work.

Detection of flammable refrigerants

Under no circumstances shall potential sources of ignition be used in the searching

for or detection of refrigerant leaks. A halide torch (or any other detector using a

naked flame) shall not be used.

The following leak detection methods are deemed acceptable for all refrigerant

systems.

Electronic leak detectors may be used to detect refrigerant leaks but, in the case of

flammable refrigerants, the sensitivity may not be adequate, or may need re-cali-

bration. (Detection equipment shall be calibrated in a refrigerant-free area.) Ensure

that the detector is not a potential source of ignition and is suitable for the refrigerant

used. Leak detection equipment shall be set at a percentage of the LFL of the refrig-

erant and shall be calibrated to the refrigerant employed, and the appropriate

percentage of gas (25% maximum) is confirmed.

Leak detection fluids are also suitable for use with most refrigerants but the use of

detergents containing chlorine shall be avoided as the chlorine may react with the

refrigerant and corrode the copper pipe-work.

NOTE: Examples of leak detection fluids are

- bubble method,

- fluorescent method agents.

Specialist’s Manual

Cylinders shall be kept in an appropriate position according to the instructions.

Label the system when charging is complete (if not already).

Extreme care shall be taken not to overfill the refrigerating system.

Ensure that the refrigerating system is earthed prior to charging the system with

refrigerant.

- 5 -

Specialist’s Manual

Ensure that contamination of different refrigerants does not occur when using

charging equipment. Hoses or lines shall be as short as possible to minimise the

amount of refrigerant contained in them.

Prior to recharging the system, it shall be pressure-tested with the appropriate purg-

ing gas. The system shall be leak-tested on completion of charging but prior to com-

missioning. A follow up leak test shall be carried out prior to leaving the site.

spheric pressure to enable work to take place. This operation is absolutely vital if

brazing operations on the pipe-work are to take place.

Ensure that the outlet for the vacuum pump is not close to any potential ignition

sources and that ventilation is available.

Charging procedures

In additon to conventional charging procedures, the following requirements shall be

followed.

The refrigerant charge shall be recovered into the correct recovery cylinders. For

appliances containing flammable refrigerants other than A2L refrigerants, the

system shall be purged with oxygen-free nitrogen to render the appliance safe for

flammable refrigerants. This process may need to be repeated several times. Com-

pressed air or oxygen shall not be used for purging refrigerant systems.

If a leak is suspected, all naked flames shall be removed/extinguished.

If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall

be recovered from the system, or isolated (by means of shut off valves) in a part of

the system remote from the leak. Removal of refrigerant shall be according to

clause IEC60335-2-40:2018 Annex DD.9 .

Removal and evacuation

When breaking into the refrigerant circuit to make repairs - or for any other purpose

- conventional procedures shall be used. However, for flammable refrigerants it is

important that best practice is followed since flammability is a consideration. The

following procedure shall be adhered to:

For appliances containing flammable refrigerants, other than A2L refrigerants,

refrigerants purging shall be achieved by breaking the vacuum in the system with

oxygen-free nitrogen and continuing to fill until the working pressure is achieved,

then venting to atmosphere, and finally pulling down to a vacuum. This process

shall be repeated until no refrigerant is within the system. When the final

oxygen-free nitrogen charge is used, the system shall be vented down to atmo-

Recovery

When removing refrigerant from a system, either for servicing or decommissioning,

it is recommended good practice that all refrigerants are removed safely.

Equipment shall be labelled stating that it has been de-commissioned and emptied

of refrigerant. The label shall be dated and signed. For appliances containing flam-

mable refrigerants, ensure that there are labels on the equipment stating the equip-

When transferring refrigerant into cylinders, ensure that only appropriate refrigerant

recovery cylinders are employed. Ensure that the correct number of cylinders for

holding the total system charge are available. All cylinders to be used are designat-

ed for the recovered refrigerant and labelled for that refrigerant (i.e. special cylin-

- 6 -

ders for the recovery of refrigerant). Cylinders shall be complete with pressure-re-

lief valve and associated shut-off valves in good working order. Empty recovery

cylinders are evacuated and, if possible, cooled before recovery occurs.

The recovery equipment shall be in good working order with a set of instructions

concerning the equipment that is at hand and shall be suitable for the recovery of all

appropriate refrigerants including, when applicable, flammable refrigerants. In ad-

dition, a set of calibrated weighing scales shall be available and in good working

condition. Before using the recovery machine, check that it is in satisfactory working

order, has been properly maintained and that any associated electrical components

are sealed to prevent ignition in the event of a refrigerant release. Consult manufac-

turer if in doubt.

The recovered refrigerant shall be returned to the refrigerant supplier in the correct

recovery cylinder, and the relevant waste transfer note arranged. Do not mix refrig-

erants in recovery units and especially not in cylinders.

If compressors or compressor oils are to be removed, ensure that they have been

evacuated to an acceptable level to make certain that flammable refrigerant does

not remain within the lubricant. The evacuation process shall be carried out prior to

returning the compressor to the suppliers. Only electric heating to the compressor

body shall be employed to accelerate this process. When oil is drained from a

system, it shall be carried out safely.
